The EdgeReady platform allows the EdgeReady Apps to connect to Bluetooth devices through the bluetooth component. The logic for this connection can be implemented using the following blocks:

BTDeviceGetList

This block retrieves the list of bluetooth devices that are available nearby. It has two callback functions:

  • The Discovered list function retrieves the available devices in the range
  • The Disappeared list function retrieves the devices that has gone out of range

   await __er.getDeviceList(async function(list){

  },
  async function(list){

  });

}

BTPairDevice

This block enables device pairing based on device ID

  });

}

BTUnPairDevice

This block enables unpairing of device based on device ID.

  });

}

BTConnectDevice

This block connects to a specific bluetooth device based on device ID.

async function er_1698139457_click(e,obj,index){
   await __er.connect((await __er.getState("deviceID")),async function(){

}

BTDisconnectDevice

This block disconnects from a specific bluetooth device based on device ID.

  },
  async function(err){

  });

}

BTListenDevice

This block is used to receive the data from the connected bluetooth device.

async function er_1698139457_click(e,obj,index){
   await __er.listen("",async function(obj){

  });

}

BTCommandDevice

This block sends commands to a bluetooth device based on device ID. For example, if a printer is the bluetooth device, this block sends the data that is to be printed.
